Application filed September 26, 1913. Serial No. 792,054.

To all whom. it may concern:

Be it known that I, GUY P. MGLAUGHLIN, a subject of the King of England. residing in Stockholm. in the county of Aroostook, in the State of Maine, have invented certain new and useful Improvements in Ironinglloards, of which the following is a specification. reference being had to the accompanying drawings, forming a part hereof.

This invention relates to ironing boards provided with folding legs movable to any one of several positions to vary the height of the board.

It has for its principal object to improve generally the construction of boards of this type. particularly in regard to such features of construction as the locking detent for the legs. the guide for the detent and the rackhar therefor.

in accordance with the present inven' tion the improved board is provided also with a sleeve board mounted slidabl v on the under face of the main board and preferably within the same guide with the detent for the legs. This sleeve board when moved inward .to its position under the main board is held therein by a friction detent and the inner end of the board bears against a spring which, upon the release of the friction clamp. moves the board initially toward its outward position so that it may be grasped readily and drawn outwardly to any desired extent.

Other improvements will appear hereinafter, reference now being had to the aceompanying drawings for a detailed description of the invention.

In these drawings-Figure 1 is a View in side elevation of an ironing board embodying the present improvements, the legs being shown in folded position. Fig. 2 is a similar view. the legs being shown unfolded to elevate the board, and part of the sleeve board being shown in section. Fig. 3 is a view of the underside of the board with the legs in the position shown in Fig. Fig. 4: is a fragmentary view in vertical section taken through the center of the board and showing in detail the improved detent for the legs. Fig. 5 is a sectional view taken on the plane indicated by the line 55 of Fig. 2 and looking in the direction of the arrows. Fig. 6 is a view partly in section taken on the plane indicated by the line 6-6 of Fig. 2 and looking in the direction of the arrows and showing particularly the sliding engagement between the detent casing and the guide. Fig. 7 is a fragmentary view looking at the under side of the guide and showing one of the teeth of the rack bar and the end locking aperture in the guide, the detent casing being omitted in the interest of clearness.

The ironing board proper a has hinged thereto at one end. as by a pintle b. a pair of legs 6 to which are pivotally connected in the usual manner, another pair of legs 0, the upper ends of the latter being hingedly connected to a casing (Z slidably mounted in a rigid channeled guide a secured to the under face of the board and extending longitudinally thereof, the right angled flanges of the guide partially embracing and retaining the casing cl in position. In the base of the guide a for a suitable distance are struck up teeth a forming a. rack-bar with the teeth of which cooperates a springpressed detent e mounted within the casing (Z. The detent e is operatively connected to a suitable lever 6. one end of which may protrude through an opening in the casing (Z to facilitate manual operation of the lever whereby the detent may be disengaged from the teeth a of the rack-bar. It will be observed that the contour of each tooth a per mits thedetent e to slide freely thereover in one direction, as for instance, when the board is raised and the legs move outwardly toward their extended position under the action of gravity. However, when the legs are in folded position. as illustrated in Fig. 1, it is desirable to have the casing d locked against movement in either direction and accordingly a suitable aperture o in the base of the guide a is formed to receive the detent. Of course, the detent may be retracted from this aperture manually by rocking the lever e, as will be understood.

l n the improved construction. the guide a preferably extends substantially throughout the length of the board a so as to constitute a suitable channeled support for a sleeve board 7". preferably disposed at the opposite end of the board from the casing if. li hen this board 7 is slid inwardly to a position beneath the main board o its inner end bears hcld in this tective casing ii. The board. 7

osition against theaction of the spring 9 y a suitable spring-pressed friction clamp i pivotally connected to a manually operable lever c and supported as byra stud j passing through the lever 21' and secured Within the side walls of a casing is through which may pass also the supporting pin 1) for the legs 6. The friction clamp i normally is pressed against the under face of the sleeve board f so as to hold the latter in fixed position, by

7 reason of the action of a suitable leaf spring l'operatively disposed with respect to the operating lever i. It will now appear that when the sleeve board 7 is to be used it is.

necessary only to operate manually the lever i so as to disengage the friction clamp i from the sleeve board. Immediately upon this disengagement, the compressed spring 9 becomes active to move the board f along the face while the functions of the guide both as a rack-bar and as a supporting member for the sleeve board are retained. It will also be evident that the compact and convenient arrangement of the operating parts by which the positions of the folding legs and the sleeve board are controlled add materially to the usefulness of ironing boards of the character illustrated.

Modifications in the' details of construction may be made without departing from the spirit of the present invention provided such modifications fall within the terms 0 the appended claim.

I claim as my invention:

In combination with an ironing board, an integral rigid channeled guide extending longitudinally of the board and secured fixedly to the underside thereof, a series of ratchet teeth formed in the base of the guide, a casing slidably mounted in the channels of the guide, amanually operable spring-pressed detent mounted in the casing and cooperating with the teeth, an aperture formed in the base of the guide to receive the detent and lock the same against movement in either direction, a pair of supporting legs hingedly secured to the casing, and a second pair of legs hingedly secured to the board, said pairs of legs being ivotally interconnected intermediate t eir ends.
